ChemInform Abstract: Synthesis of Perhalogenated 1,3-Dithietane S-Oxides and Thiirenes.
First published: September 11, 1990
Abstract
Two routes to perhalogenated thiirenes such as (III), (VI), and (IX) are presented: The first method consists in denitrogenation of the diazoalkane (I) and addition of the carbenoid to thiocarbonyl compounds, e.g. (II).
ChemInform Abstract
Two routes to perhalogenated thiirenes such as (III), (VI), and (IX) are presented: The first method consists in denitrogenation of the diazoalkane (I) and addition of the carbenoid to thiocarbonyl compounds, e.g. (II). The second method involves oxidation of 1,3-thietane such as (IV) and (VII), forming the corresponding 1,1-dioxides, (V) and (VIII), and subsequent thermal extrusion of SO2.
